ABSTRACT

A monitoring apparatus is disclosed which includes a receiver unit for receiving data and outputting a first alert signal based on the received data; and a docking unit comprising a converter unit which converts the first alert signal when the receiver unit is connected to the docking unit.

RELATED APPLICATION

The present application claims priority under §35 U.S.C. 119(e) to U.S. provisional application No. 60/946,760 filed Jun. 28, 2007 entitled “Signal Converting Cradle for Medical Condition Monitoring and Management System,” and assigned to the assignee of the present application, Abbott Diabetes Care, Inc. of Alameda, Calif., the disclosure of which is incorporated by reference for all purposes.

BACKGROUND

The present disclosure relates to a device for use with a medical condition monitoring and management system. Specifically, the present disclosure relates to a device for receiving a signal from a medical condition monitoring and management system and converting the received signal into a signal chosen by the user.

Detection of the level of analytes, such as glucose, lactate, oxygen, and the like, in certain individuals is vitally important to their health. For example, the monitoring of glucose is particularly important to individuals with diabetes. Diabetics may need to monitor glucose levels to determine when insulin is needed to reduce glucose levels in their bodies or when additional glucose is needed to raise the level of glucose in their bodies.

Devices have been developed for continuous or automatic monitoring of analytes, such as glucose, in the bodily fluids of a user. These devices allow a user to monitor his or her analyte levels and can further alert the user if the analyte levels reach, or fall below, a predetermined threshold level. If an individual is using such an analyte monitoring device, it is also important to detect any malfunction within the monitoring device. Some examples of such devices are illustrated in U.S. Pat. No. 6,175,752, and in US Patent Application Publication No. 2004/0186365 filed Dec. 26, 2003 entitled “Continuous Glucose Monitoring System and Methods of Use”. Devices and systems for management of the analyte level may also be included in the analyte monitoring system. An example of an analyte management system is an insulin pump, which may manage the analyte level by delivering a dose of insulin to the user in response to the glucose levels of the user.

In some instances, a user's analyte level may become so low that the user may feel lightheaded, disoriented or confused. In these instances, the analyte monitoring system must be sufficiently loud, so as to alert the user to the potentially dangerous condition and allow the user to correct the problem. A user is particularly vulnerable to the above scenario during nighttime or other sleep periods. A user whose analyte levels severely drop may have a difficult time hearing the alarm, especially if the user is already asleep.

One solution to the above problem is to integrate larger and more power speakers, or amplifiers, directly into the analyte monitoring device. However, this solution may unnecessarily increase the size and circuit complexity of the device. Additionally, directly integrating the speakers or amplifiers into the analyte monitoring device will result in an increased cost of the device.

As a result, there is need of a low cost system, which does not affect the size and circuit complexity of the analyte monitoring device.

DETAILED DESCRIPTION

The present disclosure will now be described more fully with reference to the accompanying figures, in which exemplary embodiments of the disclosure are shown. The figures referred to herein are not necessarily drawn to scale, with some components and features being exaggerated for clarity. Like reference numerals in the figures denote like elements.

It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting, since the scope of the present disclosure will be limited only by the appended claims. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It must be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.

As will be apparent to those of skill in the art upon reading this disclosure, each of the individual embodiments described and illustrated herein has discrete components and features which may be readily separated from or combined with the features of any of the other several embodiments without departing from the scope or spirit of the present disclosure.

FIG. 1 shows a data monitoring and management system such as, for example, an analyte (e.g., glucose) monitoring system 100 in accordance with certain embodiments. Embodiments of the subject disclosure are further described primarily with respect to glucose monitoring devices and systems, and methods of glucose detection, for convenience only and such description is in no way intended to limit the scope of the disclosure. It is to be understood that the analyte monitoring system may be configured to monitor a variety of analytes at the same time or at different times.

Additionally, one exemplary embodiment the analyte monitoring system may include an analyte management system, such as an insulin pump. Thus, it is to be understood that the following description is directed to an analyte (for example, glucose) monitoring system for convenience only and such description is in no way intended to limit the scope of the disclosure.

The analyte monitoring system 100 may be a continuous monitoring system, or semi-continuous, or a discrete monitoring system. In a multi-component environment, each component may be configured to be uniquely identified by one or more of the other components in the system so that communication conflict may be readily resolved between the various components within the analyte monitoring system 100. For example, unique IDs, communication channels, and the like, may be used.

Analytes that may be monitored include, but are not limited to, acetyl choline, amylase, bilirubin, cholesterol, chorionic gonadotropin, creatine kinase (e.g., CK-MB), creatine, creatinine, DNA, fructosamine, glucose, glutamine, growth hormones, hormones, ketone bodies, lactate, peroxide, prostate-specific antigen, prothrombin, RNA, thyroid stimulating hormone, and troponin. The concentration of drugs, such as, for example, antibiotics (e.g., gentamicin, vancomycin, and the like), digitoxin, digoxin, drugs of abuse, theophylline, and warfarin, may also be monitored. In those exemplary embodiments that monitor more than one analyte, the analytes may be monitored at the same or different times.

Additionally, within the scope of the present disclosure, other physiological or medical conditions or medications may be monitored for treatment, such as for example, monitoring for pain medication, cancer medication, or immuno-suppressant medication, nonlimiting examples of which may include cyclosporine, tacrolimus, or corticosteroids.

Moreover, the description herein is directed primarily to electrochemical sensors for convenience only and is in no way intended to limit the scope of the disclosure. Other sensors and sensor systems are contemplated. Such include, but are not limited to, optical sensors, colorimetric sensors, and sensors that detect hydrogen peroxide to infer analyte levels.

Referring to FIG. 1, the analyte monitoring system 100 includes a sensor 101, a data processing unit 102 connectable to the sensor 101, and a primary receiver unit 104, which is configured to communicate with the data processing unit 102 via a communication link 103. In certain embodiments, the primary receiver unit 104 may be further configured to transmit data to a data processing terminal 105 to evaluate or otherwise process or format data received by the primary receiver unit 104. The data processing terminal 105 may be configured to receive data directly from the data processing unit 102 via a communication link which may optionally be configured for bi-directional communication. Further, the data processing unit 102 may include a transmitter or a transceiver to transmit and/or receive data to and/or from the primary receiver unit 104 and/or the data processing terminal 105 and/or optionally the secondary receiver unit 106 and/or the docking unit 300, which is described in greater detail below.

Also shown in FIG. 1 is an optional secondary receiver unit 106 which is operatively coupled to the communication link and configured to receive data transmitted from the data processing unit 102. The secondary receiver unit 106 may be configured to communicate with the primary receiver unit 104, as well as the data processing terminal 105. The secondary receiver unit 106 may be configured for bi-directional wireless communication with each of the primary receiver unit 104 and the data processing terminal 105. In certain embodiments the secondary receiver unit 106 may be a de-featured receiver as compared to the primary receiver, i.e., the secondary receiver may include a limited or minimal number of functions and features as compared with the primary receiver unit 104. As such, the secondary receiver unit 106 may include a smaller (in one or more, including all, dimensions), compact housing or embodied in a device such as a wrist watch, arm band, etc., for example. Alternatively, the secondary receiver unit 106 may be configured with the same or substantially similar functions and features as the primary receiver unit 104.

The primary and secondary receiver units 104 and 106 may also include a docking portion to be mated with a docking unit for placement by, e.g., the bedside for night time monitoring, and/or a bi-directional communication device. The docking unit will be described in greater detail below.

In certain embodiments, the sensor 101 is physically positioned in or on the body of a user whose analyte level is being monitored. The sensor 101 may be configured to at least periodically sample the analyte level of the user and convert the sampled analyte level into a corresponding signal for transmission by the data processing unit 102. The data processing unit 102 performs data processing functions, where such functions may include but are not limited to, filtering and encoding of data signals, each of which corresponds to a sampled analyte level of the user, for transmission to a receiver unit (104 or 106) via the communication link 103.

An exemplary embodiment of the receiver unit is illustrated in block form in FIG. 2, and includes a receiver 20 to receive data from the data processing unit 102, an analyzer 22 to evaluate the data, a display 24 to provide information to the user, and an alarm system 26 to warn the user when a condition arises. The receiver unit (104 or 106) may also optionally include data storage 28, a transmitter 30 and an input device 32.

In one exemplary embodiment, the alarm system 26 of a receiver unit (104 or 106) is triggered when the analyte level of a user equals, or falls below, a predetermined threshold analyte level. Each condition of the user that can trigger an alarm may have a different alarm activation condition.

The alarm system 26 may also contain one or more individual alarms. Each of the alarms may be individually activated to indicate one or more conditions associated with an analyte. Additionally, the analyte monitoring system 100 may include several threshold levels for each analyte to be measured, and an individual alarm corresponding to each threshold level. When the alarm is activated, the alarm system 26 outputs an alert signal corresponding to the activated alarm. In some embodiments, the alarms are auditory, e.g., with a different tone, note or volume indicating different conditions. In another exemplary embodiment of the present disclosure, various tones of the alarm system 26 may indicate varying urgency levels of a user's need to correct a problem, such as when the analyte level is dangerously low. Additionally, other exemplary embodiments of the present disclosure include an analyte monitoring system 100 which may predict future analyte levels. For example, the analyte monitoring system 100 may detect the rate of change of analyte levels in the user and predict the analyte level of the user at a future point in time. As such, certain types of alarms may warn the user that he will reach a predetermined analyte threshold level within a certain time, if no action is taken.

The varying types of alarms described above may be pre-associated with various conditions by default, may be set by the user or may be set by any other authorized person. This allows the user, or another authorized person, to customize the device according to the needs, or treatment requirements of the user. For example, some users will want to have a series of escalating alarms to respond to varying glucose levels. In this example, a user may set a medium level audio alarm clock type of alarm to indicate a projected low analyte level 30 minutes in advance, followed by a maximum level audio alarm recorded in a parent's voice calling the user's name to indicate that a low threshold has been reached, followed by the maximum level audio alarm accompanied by flashing lights when the user reaches an analyte level 10 mg/dL below the low threshold.

With regard to FIG. 3A, there is illustrated a side view of a docking unit 300 in accordance with an exemplary embodiment of the present disclosure. As described above, the receiver unit (104 or 106) may be mated with the docking unit 300. As shown in FIG. 3A, the docking unit 300 may include a speaker 310, a recording medium 320 and a connector 330. In one exemplary embodiment, the docking unit 300 may be used to charge the receiver unit (104 or 106). Additionally, in one exemplary embodiment the speaker 310 can be a plurality of speakers.

The interrelationship between the docking unit 300 and the primary and secondary receiver units (104 and 106) will now be described. In one exemplary embodiment, the primary receiver unit 104 may provide functions similar to those of the docking unit 300. That is, the primary receiver unit 104 may include speakers and louder alarm settings. With regard to those features of the primary receiver 104 and the docking unit 300 that overlap, the docking unit simply provides an additional alarm capability. The docking unit 300 also may also provide additional features, which may not be included in the primary receiver unit 104, as described below.

With regard to the secondary receiver unit 106, as mentioned above, the secondary receiver unit 106 may include a limited or minimal number of functions and features as compared with the primary receiver unit 104. Thus, with relation to the secondary receiver unit 104, the docking unit 300 provides the user with the ability to split functionality between the docking unit 300 and the receiver unit 106, as desired. For example, by removing the large speakers and/or amplifiers from the receiver unit 106, the receiver unit 106 may be made lighter, smaller and less expensive, while retaining the ability to effectively awaken or alert the user as needed. It is to be understood that any, all or none of the features of the secondary receiver unit 106 may be transferred to the docking unit 300.

FIG. 3B shows a profile view of the docking unit 300 illustrated in FIG. 3A. According to one exemplary embodiment, the docking unit 300 may further include an input device 380 and a charge indicator 390, such as for example, a light which indicates that the receiver unit (104 or 106) is charging.

In one exemplary embodiment, the connector 330 is used as a mating station between a docking portion of the receiver unit (104 or 106) and the docking unit 300. In another exemplary embodiment, the connector 330 may be used to communicate between the docking unit 300 and/or the receiver units (104 or 106) and/or the sensor 101 and/or any other device, such as a computer. In one exemplary embodiment, the connector 330 of the docking unit 300 may be configured for bi-directional communication with the above-listed devices. Varying types of connections which may be used are described in greater detail below, and include wired and wireless protocols. In this exemplary embodiment, when the receiver unit (104 or 106) is connected to the connector 330 of the docking unit 300, the docking unit 300 receives the alert signal output by the alarm system 26 of the receiver unit (104 or 106), converts the alert signal of the receiver unit (104 or 106) into a second alert signal and outputs the second alert signal to the speaker 310. The conversion can be accomplished using a converter (not shown) located within the docking unit 300.

As shown in FIGS. 3C and 3D, in one exemplary embodiment, the docking unit 300 of FIG. 3A may be connected to the power supply 360. In this exemplary embodiment, the docking unit 300 may further include a control circuit 340 for controlling a light source 370. In one exemplary embodiment, the light source 370 may be provided directly on the docking unit 300 or may be an external light source. Similarly, the control circuit 340 may be provided directly on the docking unit 300, or may be an outside circuit. (Compare FIG. 3C and FIG. 3D). In embodiments where the light source 370 is an external light source, such as a lamp, the control unit 340 may be wirelessly or physically connected to the external light source 370. Additionally, in one exemplary embodiment, the control unit 340 of the docking unit 300 may turn the light source 370 on and off in accordance with the first or second alert signal.

FIG. 4 is a block diagram of the docking unit 300 according to an exemplary embodiment of the present disclosure. Some exemplary functions will now be explained using the block diagram of FIG. 4. In one exemplary embodiment, the connector 330 receives the first alert signal of the alarm system 26 of the receiver unit (104 or 106) and sends it to the converter 350. The converter 350 then amplifies the first alert signal to generate a louder, second alert signal. That is, in this exemplary embodiment, the docking unit 300 amplifies the sound of the alarm, when the alarm is activated in the receiver unit (104 or 106). In one exemplary embodiment, both the receiver unit (104 or 106) and the docking unit 300 emit an auditory alarm. In one exemplary embodiment, the tone of the auditory alarm emitted by the docking unit 300 and the tone of the auditory alarm emitted by the receiver unit (104 or 106) may be the same. In another exemplary embodiment the tone of the auditory alarm emitted by the docking unit 300 and the receiver unit (104 or 106) may be different and clash when emitted.

With further reference to FIG. 4, in another exemplary embodiment of the disclosure, the connector 300 receives the first alert signal output by the receiver unit (104 or 106) and sends it to the converter 350. The converter 350 then outputs the same first alert signal through the speaker 310 of the docking unit 300. In this exemplary embodiment, the speaker 310 of the docking unit 300 has a maximum volume that is louder than the volume of the receiver unit's speakers. As such, the receiver units 104 and 106 are not required to have powerful speakers. Reducing the size of the speakers on the receiver units 104 and 106 may allow the receiver units to be more compact, inexpensive, and/or durable.

In yet another exemplary embodiment, the connector 330 may receive the first alert signal output by the receiver unit (104 or 106) and send it to the converter 350. The converter 350 may then replace or otherwise modify the first alert signal with a second alert signal. The converter 350 then outputs the second alert signal through the speaker 310. In one exemplary embodiment, the recoding medium 320 may be used to record an alert message, wherein the recorded message will act as the second alert signal and will replace the first alert signal of the receiver unit (104 or 106). For example, if the analyte monitoring system 100 is to be used for a child, the recorded message may be the voice of a parent or guardian. In another exemplary embodiment, the recorded message may be the voice of a doctor, the voice of a celebrity, or the voice of any other person. Additionally, there may be several recorded messages which correspond to the several possible individual alarms of the alarm system 26 of the receiver unit (104 or 106). Some examples of messages that may correspond to varying alarms may be: “Check glucose!,” “Wake up!,” “Low glucose!,” “Glucose is 50 mg/dL,” “High glucose! Check Keytones!,” “Check insulin delivery!,” “Check pump!” or “Check sensor!.” These messages may be pre-programmed into the system, may be customized for a specific user or may be edited by the user. In other embodiments, these messages may be downloaded over a data network such as a local area network, or the internet.

In one exemplary embodiment, the docking unit 300 may also include an input device 380 such as a keypad or keyboard. The input device 380 may allow numeric or alphanumeric input. The input device 380 may also include buttons, keys, or the like which initiate functions of and/or provide input to the docking unit 300. Such functions may include changing the settings, alarm types, volume levels or alarm conditions of the docking unit 300 but are not limited to the above. For example, the user may choose whether a pre-recorded voice will be used as an alarm, choose the volume level and associate that alarm with a specific condition. Additional functions include interaction between the docking unit 300 and a receiver unit (104 or 106), or any other device. For example, as previously mentioned, an alert signal may be any pre-recorded sound. These sounds may be recorded on any medium and then transferred to the docking unit 300, via the connector 330 and the input device 380, to be used as the alert signal. Similarly, alarm conditions and types may be defined for a treatment type, or individual user, using computer software. These predefined settings may also be downloaded to the docking unit 300 via the connector 330 and the input device 380.

In another exemplary embodiment, the input device 380 may be a screen to display the settings to the user. Moreover, the input device 380 may be any combination of the above, including a touch screen for interacting with the docking unit 300 as described above.

The receiver unit (104 or 106) may be connected to the docking unit 300 using any type of connection. For example, the docking unit 300 may be connected to the primary and/or secondary receiver unit (104 and 106) via a physical connection, a wireless connection or both. In one exemplary embodiment, the docking unit 300 may detect the primary and/or secondary receiver (104 or 106), when the receiver units (104 and 106) are within a predetermined distance of the docking unit 300.

In another exemplary embodiment, one receiver unit (104 or 106) may be physically connected to the docking unit, for example while charging. In this exemplary embodiment, the docking unit may still detect the other receiver unit (104 or 106), if that receiver unit is within a predetermined distance of the docking unit 300.

In another exemplary embodiment, the connection between the receiver unit (104 or 106) and the docking unit may be both a physical and wireless connection. That is, the charging function, for example, may be performed via a physical connection, while the receiver unit (104 or 106) may otherwise communicate with the docking unit 300, such as for example sending an alert signal to the docking unit 300, via a wireless connection. It is to be understood that any combination of functions and connection types may be used.

For example, a mini-USB is one component that may provide for a physical connection between the docking unit and the receiver unit (104 or 106), or the docking unit 300 and any other device. The mini-USB can be used to pass electricity into the receiver unit (104 or 106) to charge the battery and can be also used as a conduit to upload and download information between a receiver unit (104 or 106) and the docking unit 300 and/or between the docking unit 300 and a computer, or any other device. It is to be understood that any of these functions may be accomplished using either a physical or wireless connection.

In embodiments where a wireless connection is used, the remote connection may use one or more of: an RF communication protocol, an infrared communication protocol, a Bluetooth enabled communication protocol, an 802.11x wireless communication protocol, or an equivalent wireless communication protocol which would allow secure, wireless communication of several units (for example, per HIPPA requirements), while avoiding potential data collision and interference.

Accordingly, a monitoring apparatus in one aspect may include a receiver unit which receives medical data of a patient and outputs a first alert signal based on the received data, and a docking unit comprising a converter unit which converts the first alert signal when the receiver unit is connected to the docking unit.

The received medical data may include data corresponding to the analyte level of a patient, and further, where the receiver unit may be configured to output the first alert signal if the analyte level of the patient reaches a predetermined threshold level.

In another aspect, the converter unit may be configured to convert the first alert signal into a second alert signal, where the first alert signal output by the receiver unit may be an auditory signal, and the second alert signal generated by the converter unit may be a louder auditory signal. In another embodiment, the first alert signal may be amplified to generate the second alert signal.

In still another aspect, the converter unit may replace the first alert signal with the second alert signal.

The apparatus may include a recording medium for recording a sound to be used as the second alert signal.

Also, the docking unit may include a charging unit for charging the power supply of the receiver unit when the receiver unit is connected to the docking unit.

Still further, the docking unit may include a light control unit, which regulates a light source based on the first alert signal, where the light source may include an external light source.

A monitoring apparatus in accordance with another aspect includes a sensor for monitoring an analyte level of a user, a receiver unit which receives data from the sensor and indicates the level of the analyte, wherein the receiver unit outputs a first alert signal if the analyte level reaches a predetermined threshold level, and a docking unit comprising a converter unit which converts the first alert signal when the receiver unit is connected to the docking unit.

The converter unit may be convert the first alert signal into a second alert signal, where the first alert signal output by the receiver unit may include an auditory signal, and the second alert signal generated by the converter unit may include a louder auditory signal.

Also, the first alert signal may be amplified to generate the second alert signal.
